Abstract
An optical phase shifter array includes: 1˜noptical-splitting elements, wherein each has an input end, a first output end and a second output end, and the input end of the 1optical-splitting element receives an input light and outputs an evenly distributed optical signal to the optical-splitting element of the next stage, and n is a positive integer above 1; a plurality of first optical waveguides respectively connected to the input end of the optical-splitting element odd-numbered of the next stage and the first output end of the optical-splitting element of the previous stage; a plurality of second optical waveguides respectively connected to the input end of the optical-splitting-element even-numbered of the previous stage; and phase shifters of the 1to the kstage, which makes the optical signal passing through the optical waveguides produce a phase shift by heating or electro-optic effects.
